B. is a pipe by which he exhaust gases are 9 eenstruetlonegl'lg. 2 1s .ee-end viewpartly in 2 soeces led to s pipe R which is wiihiu the helios' stsnd. At the inner end of this pipe is e Voriicsl portion R The upper end of ibis portion of the pipe is surrounded by en cumuler chamber U. Around the upper end of this chamber is s iisuge to which is secured e iisnge which is m, the bottom of e, closed chamber T. The top of he vertical pipe R2 is connected to the lower end of s funnel shaped lining S (see Fiff. i) which. is Wihin 4the chamber. The exhaust gases from the enginetherefore pass up es shown by the sro rows in Fig. 1 into the funnel S and fromV iis open top pass downward between the funnel and the chsmberT and through openings in ihe bottom of the chamber to the enuuler chamber U from which they pass into .e pipe V by which they are-conveyed ewsy.

X is e cap covering the chamber 'T so that oir passing into the .upper end of the coil es A is iakenfrom within this cap and wouid therefore be to some exteni'I heated. From the chamber C the eir passes through e number of small passages D to the conedf outlet F of the atomizer. is the sir issues-from the passages D it ianpinges on the ends of nozzles E. These nozzles here liquid hydrocarbon supplied to them through the pipes E from e supply of liquid hydrocarbon which is alwejfs kept at the seme level, or by other suitable means. The nozzles here very line The sir impinging upon them converts ihe' eil issuing from them iuto spray and the heet of the sir i vsporizes more or less of the oil.. The het spray and vapor thus formed pass upward through F where they ere mixed with e. fur; ther smali qusndty of sir passing through the holes G. On issuing from F ihey pees into e. coned passage lll where they receive s furiher edmixture of air end the explosive mixture so formed passes through the valve L and poriy M to the cylinder of the engine Where after being compressed it is exploded. if desired the hot, spray and vapor before receiviug this further sdmixture of air might be still further heated by beingpzissed through e heated passage. I however prefer that they shnould at once receive this further edmixiure oi 'air as above described. The cened passage ll leads from e. jacket; H' by which the atomizer is surrounded. Air is supplied to this jacket through s pipe 114 which passes from the interior of the hollow standil'en which the cyliud-r of the engine is mounted.
